Problems solved by technology

But for linear projects like highway projects or railway projects, which are hundreds of meters away and obviously cover the entire line of atmospheric environment monitoring points, not only the cost is high, but also the maintenance cost is very expensive. How can we develop a set of vehicle-mounte

Embodiment

[0018] Embodiment: a kind of monitoring method that is used for the atmospheric environment PM2.5 monitoring device of engineering construction is as follows,

[0019] ① Close the first exhaust channel 12, the second exhaust channel 13, the first air inlet 14, the second air inlet 15, the first air outlet 10 and the second air outlet 11.

[0020] ② Turn on the data acquisition system and power supply system.

[0021] ③ Open the first gas collection port 16 and the second gas collection port 18, so that the gas enters the gas distribution channel 19 through the second gas collection port 18, and the gas distribution channel 19 is centrifuged to sieve the gas after removing PM2.5 to the particle retainer 20. Sieve the PM2.5 gas to the air supply channel 17, and send it to the dust equipment chassis 1 through the first gas collection port 16; the scattering plate 4 disperses the PM2.5 gas, and the light-emitting element 5 emits light to cause light scattering of the PM2.5 gas , ...

Abstract

The invention provides an atmospheric environment PM2.5 monitoring device for engineering construction. The device comprises a dust equipment chassis (1), a light receiving element (2), a receiving plate (3), a scatter plate (4), a light emitting element ( 5), a first exhaust pipeline (6), a second exhaust pipeline (7), a first fan motor (8), a second fan motor (9), a first exhaust port (10), a second exhaust port (11), a first exhaust passage (12), a second exhaust passage (13), a first air inlet (14), a second air inlet (15), a first gas collection port (16), a gas supply passage (17), a second gas collection port (18), a gas distribution passage (19), a particle retention device (20), a data collection and storage system and a power supply system. The instrument can meet a self-cleaningfunction of the equipment under the heavy pollution condition of PM2.5. The PM2.5 concentration can be measured independently, or the PM2.5 concentration can be measured in a vehicle-mounted mobile manner.

Description

technical field [0001] The invention relates to the fields of engineering construction and atmospheric environment protection, especially the field of highway engineering, and specifically relates to a monitoring device for particulate matter (PM2.5) in the atmospheric environment used in engineering construction. Background technique [0002] The construction of expressways will inevitably have direct or indirect impacts on the environment to a certain extent, especially it will change the continuity and integrity of the existing natural environment and destroy the ecological balance of natural environmental protection. By installing various atmospheric environment monitoring probes and systems during the project construction process, the environmental pollution caused by project construction can be effectively supervised. But for linear projects like highway projects or railway projects, which are hundreds of meters away and obviously cover the entire line of atmospheric e...
